Mary Morales was 36 when her body was found alongside Interstate 91 in Vernon, Vermont, on March 4, 1999. An autopsy confirmed her death was a homicide. Investigators say Morales had worked at Unicare, Inc. in Springfield, Massachusetts, on March 3 and likely accepted a ride home that day; they also believe she knew her killer.

Authorities from both the Vermont and Massachusetts State Police, along with the Hampden County District Attorney’s office, concluded the killing likely occurred in Massachusetts and that her body was transported and left by the interstate in Vermont. Investigators have long suspected the slaying was connected to Morales’s husband, Edgardo Morales, who was known to law enforcement for drug-related activity in Springfield; detectives have suggested the killing may have been retaliatory or meant to send a message.

Springfield police have identified persons of interest over the years, but no arrests have been announced and the case remains unsolved. If anyone knew Mary, her movements on March 3–4, 1999, or has information about who drove her that day, please share what is known.
